Question
t's 7 p.m. in Kenya. A restaurant is crowded. No one is talking. Everyone is watching the news on TV. Some walked miles to get there. This is common in much of Africa. Many people have no electricity. It's one of the biggest problems facing the second largest continent.
In sub-Saharan Africa, there are about 625 million people living without electric power. Most of them are in isolated areas. There are no electrical grids. And in other places the electricity doesn't work all of the time. In Ghana, people call the power dum/sor. The name means "off/on." That's because the electricity flickers so much.
But Africa does receive a lot of sunshine. This makes it a good place for solar panels. Solar panels used to be expensive. But costs have gone down. Now they are affordable. Businesspeople are working on ways to bring solar power to more areas.
There are many ways to do this. One idea is microgrids. Microgrids are small electrical grids. Each grid is powered by solar energy. The Green Village Energy company put up 126 solar panels in Bisanti, Nigeria. The panels power the whole town.
Another idea is kits that can power a single house. Each kit would have a small solar panel, battery, wires, and plugs. Several companies are trying out this method in Africa. One of them is Lumos, in Nigeria. It makes enough cheap power for two to three hours of TV watching and cell phone charging. Another is M-Kopa. It has brought power to more than 600,000 houses. M-Kopa kits come with a fan, lights, and a TV that can get 30 free channels.
Fenix is a company in Uganda. Its kits can power everything from a single cell phone charger to a stove to a satellite TV. The kits are not expensive. But they're not free. Customers pay a fee at the beginning. Then they make small payments for years. At the end, they own the kit. Then power is free.
Electricity is greatly changing lives. Even a fan can make a big difference. Many parts of Africa are very hot. Houses often don't have windows or air conditioners. Power also allows for refrigeration. That means hospitals can store vaccines. Students also benefit. They have light at night so they can read and study.
In Africa, phones were once rare. Many people lived beyond the reach of telephone lines. But cellular networks changed things. They brought phone service across the continent. The hope is that off-grid solar could be similar. It could bring power to places where it once seemed out of reach.

The sentence that expresses an opinion is:
**"The best kind of energy is solar power."**
This statement reflects a subjective belief about solar power, rather than a factual statement. The other sentences present facts or observations about solar panels, lack of electricity, and the features of energy kits.
